ok so the 1.5L kenne bell i had on my cobra crapped out on me so i shelled out the money and had it rebuilt they honed it out to a 2.0L and replaced all the parts because they dont make a 1.5L anymore....so heres my problem i have no clue how much boost i can run without blowin it up. Does anyone know how much i can run? I think i am running 6psi right now im pretty sure of it.

It's impossible to give an accurate psi. It depends on so many things like octane, ignition timing, compression etc. 8 should be safe, the bigger bore lowers the discharge temperature. I advise looking into water injection if planning going over that. Best way would be monitoring discharge temperature and listening for knocking or pinging.

yeah it's impossible to say with certainty. i would say around 8 if it's a DD, much more than that and you can have some issues. good tune, good maintenence, and not beating on it from every stoplight will keep it running for a long time.
